Deze omschrijven staat op de site van Effax (helaas in het engels):
The fat-free care and cleaning agent. With regular application leather becomes skidproof and tearproof. Takes the place of saddle soap. Greasy spots on equestrian clothing are things of the past. Sweat residues are removed quickly and permanently. Effax Leather Combi is polishable and does not attract dust.
Maar wat ik daaruit begrijp vervangt het zadelzeep.
